SHUTTLE-PROTECTOR.

SPEGLFEGATION formingpart of Letters Patent No. 676,321, dated June 1 1,1901.

. Application filed November 20,1900. Serial No. 37,162. (No model.)

To all whom it minty concern.-

Be itknown that I, JAMES JORDAN, a citizen of the United States,residing at Burlington, in the county of Chittenden and State ofVermont, have invented certain new and useful Improvements inShuttle-Protectors; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in shuttle-box backs; and itpertains to a particular construction of the end of the back, wherebythe wear and frequent destruction of the shuttle are prevented and theerratic movement of loose spindles is controlled.

My invention is particularly intended for use in connection with theNorthrop loom, which uses a shuttle with a self-threader at one endthereof. Owing to the shape of the end of the shuttle-box back in thisloom it is found in practice that when the shuttle in its movementsalong the race-plate catches in a dropped or loose thread or for anyother reason is directed out of its course the point of the shuttlestrikes the metallic end of the boX-back,with the result that the pointof the shuttleis frequently broken or smashed, which absolutely destroysthe shuttle for further use. WVhen the shuttle is not directedsufficiently from its course to cause the above result, theself-threader is liable to be worn by friction with the metal, and in ashort time the shuttle must be put aside. In addition to this should thebobbin in the shuttle become loosened by not being properly pressed intoits place or by the breaking of its spring it is liable to fly upward inits transfer and catch in and break the warp, so that in the actualrunning of said loom the life of the shuttle is Very short and the warpis seriously injured.

tion of the race-plate of the loom,- B my im: proved back for theshuttle-box, and O the shuttle-box plate.

My improvement consists in providing the end of the shuttle-box backwith a yielding protector a, which is attached to the end of the top Dof the shuttle-box back B and has its end 5 projecting downward belowthe inner face of the said top D and its end 0 curved, as shown, for thepurpose of directing the shuttle downward or toward the bottom ofthebox-plate 0. Its bottom extends down sufficiently far to form ashoulder S to-catch the end of the bobbin should it fly upward from theshuttle in its transfer from not being properly pressed down in itsplace in the shuttle or by reason of the breaking of its springs, so asto prevent its breaking through and materially injuring the warp.

This protector is composed of leather, rubber, or wood and may beattached in several ways to the end of the top D; but in either event itis made detachable, so that should it become injured by thecontacttherewith of the metallic end of the shuttle or become worn itcan be readily detached and another substituted therefor. By thisconstruction of the top of the shuttle-box back the injury and Wear aremostly upon the protector, which is very cheap, as compared to theshuttle, and easilyreplacedbyanother. In actualpra-ctice it is found toavoid entirely the destruction of the end of theIshuttle and consequentincapacitation of the shuttle, and to greatly ina 1 5' Referring now tothe drawings, A is a por i crease the life of the shuttle because of thede- I ner of attaching the protector, which is accomplished by providingthe extremity of'the top of the shuttle-box with alongitudinallyextending slot or groove d, which is adapted to receive atenon or projection upon the end of the protector. In this constructionit will be noted that the protector projects below the inner face of thetop of the shuttle-box to form the shoulder S to catch a flying bobbinand has its end curved for directing the shuttle down upon the box-plateO. The protector is preferably held within the slot cl through themedium ofscrews' e, which pass through the wall' of' the slot and intothe protecton In Figs. 2 and 4 I show a slight modification in the shapeof the protector and the manner of securing it to the top of theshuttle-box. In this instance the protector consists of a block I),having right-angle end and topfto fit into the L-shaped recess G, formedacross the end of the top of the shuttle-box, while theo-uter or otherend 0 is curved similar to the corresponding end of the protector (1,(shown in Figs. 1 and 3,) and it is also similar to said protector inthat it has its under side projecting or'extending down below the innerface of the top of the shuttle-box to form thejshoulderS. Theprotectorin thisinstance serves the same purpose as the protector inFig. land operates the same way to direct the shuttle down on thebox-plate and to protect the shuttle from injury and wear and to catchthe loosebobbin. The protector b is attached through the medium of thebolt H, which passes through the rear wall of the back of the box andthrough the block, as

illustrated, and by means of which the protector is-readily and quicklyremovable therefrom in case of injury or wear to be substituted bya newone.

Itwill be noted that in both constructions theend of the top of theshuttle-box is cut out and the protector inserted in the recess orwhereby it isadapted to accomplish the pur- I poses-herein fullyexplained.

wall of the top, as shown, whereby it is more yielding than it would beif the metallic top extended entirely over the block or member.

While I have described my invention as inmake of loom where it would beadvantageous for the purposes herein described.

Having thus described my invention, what "I claim, and desire to secureby Letters Patent, is-

1. A shuttle-box back having its top provided at the entrance end with ayielding ,1 block projecting downward below the inner face thereof andhaving its outer extremity curved upward at its under side,substantially as described.

2. A shuttle-box back having its top provided with atransversely-'arranged' recess, a yielding block detachably securedwithin the said recess, the under side of the block projecting downwardbelow the face of the top and having its outer face curved upward,substantially as described.

3. A shuttle-box back havingat oneend a yielding block, the said blockhaving its outer end extending beyond the outer end of the said top,substantially as described.

4. A shuttle-box back having its top projvided at one end with ayielding shuttle-protecting block, the said block having atits inner enda shoulder adapted to engage theend of the displaced bobbin,substantially as and for the purpose described.

5. A shuttle-box back having its top provided at one end with ayielding-'shuttle-pro- .tectin g block projecting downward below theinner face thereof, the inner end of the'block having adownwardly-projecting shoulder for the purpose of engaging the end ofadisplaced bobbin, substantially as described.

6. A shuttle-box back having its top provided at one end with a yieldingshuttle-protecting block, the outer end of the said block being curvedupward and the inner end of l the said block having adownwardly-projecting shoulder for the purpose of engaging the end of adisplaced bobbin, substantially as described. groove and pro ects belowits inner face,

In testimony whereof I do affix my signature in presence of twoWitnesses.
